Logic Puzzle - Mystery Of The Light Switches..

There are three switches on the ground floor. Each
turns on one of the three light bulbs in the basement. You can turn the switches on and off and leave them in any position. 

How would you identify which switch corresponds to which light bulb, if you are only allowed one trip downstairs?

Check answer below:

Turn the first switch for a few minutes. It will get warm, right? So all you have to do then is ... switch it off, switch another one on, walk into the room with bulbs, touch them and tell which one was switched on as the first one (the warm one) and the others can be easily identified.
